Here, Nacham talks with The Hollywood Reporter about working with young Miles and reveals who he thinks Batman really is.

What has working with Miles and his family been like?

We went up to their farm in Northern California for three days. They are great and totally in it and support of it.

Does Miles know that he's a big deal now?

No, I don't think so. I think he's a really special kid. He has a real sense of self for that age. I'm interested in what he becomes because he's a special guy. He's not a huge talker. I spent a lot of time watching him play.
